Moderator Cynic Posted May 23, 2014 Moderator Share Posted May 23, 2014 Define wobble. Are we talking butt clenching terror shakes or a slight shimmy you can sense rather than feel. Can you feel it with your feet, your arse, your hands or all. Link to comment Share on other sites More sharing options...
homer382 Posted May 23, 2014 Author Share Posted May 23, 2014 i have changed all the bearing from front wheel, swing arm bearings head stock bearings i upgraded to racers. rear wheel bearings are also new and ive had a new front tyre fitted and balanced about two days ago.. @ cynic it's more that i can feel it than see it more in my hands and legs. I'm wondering if it might need to get the front aligned? Link to comment Share on other sites More sharing options...

blackhat250 Posted May 23, 2014 Share Posted May 23, 2014 Type of tyre , not suiting the bike,,, is it crossing the white lines when wobble,,? Up the pressure a bit,, Link to comment Share on other sites More sharing options...
Moderator drewpy Posted May 23, 2014 Moderator Share Posted May 23, 2014 does sitting forward or to the back change anything. How about with a pillion? tyre pressures? Link to comment Share on other sites More sharing options...
Moderator Airhead Posted May 24, 2014 Moderator Share Posted May 24, 2014 any swing arm lateral play? Link to comment Share on other sites More sharing options...
KevtheRev Posted May 24, 2014 Share Posted May 24, 2014 Make sure your tyres are the sizes recommended by Yamaha , and that the pressures are correct . Sometimes mixing tyres from different manufacturers , even if the correct sizes , can have a bad effect . Link to comment Share on other sites More sharing options...
Moderator Cynic Posted May 24, 2014 Moderator Share Posted May 24, 2014 If your feeling it with your arms and legs then its more front biased. Are the bars rubber mounted? Steering head bearings a little too tight? and front tyre would be my first inspections. Link to comment Share on other sites More sharing options...
homer382 Posted May 24, 2014 Author Share Posted May 24, 2014 Ok from the top..... no it's not crossing the white line the wobble isn't severe but noticable, the tyre is a maxxi classic as recomended to me. i have checked the front psi and it's at 32. i have no bitch seat. their is no play in the swing arm i changed the bearings last weekend and have checked them again when i had the bike up in the air doing the headstock bearings. the tyre I bought is the recomended size in the handbook 100/90-19". the bars are rubber mounted. i have done a realignment on the forks which has helped..

Dickwad Posted May 26, 2014 Share Posted May 26, 2014 Hey all you peeps i have a queery and would like some help... i have got a wobble on my xvs650. I've changed all the bearings from the front to the back, I've had my front and rear tyres checked and balanced ive also checked the frame for bad dents and cracks just to make sure but it's still there.. it only seems to occure when im between 60/70mph.. lift the wheels off the ground and (one at a time of course) spin the wheel watching the rim where the Tyre bead sits, it might not be seated evenly, if its not, let the Tyre down, push the bead off the rim (inwards), and pump it up again.

homer382 Posted May 26, 2014 Author Share Posted May 26, 2014 That was one of the first things I did. I took the new tyre right of and had a new innertube and the tyre refitted by a motorcycle workshop and got them to check it was seated properly... the only things i haven't done is replace the fork oil seals and I'm going to put another new set of front wheel bearings in just incase they are faulty as i did buy them from fleabay.. to all the others that posted i took her for a run and she still hasa small wobble.. more like a shake now..
